23/06/2020 88th ISOLDE Collaboration Committee meeting - J. Vollaire 2
Situation and organization since mid-March
• Mid-March the facility was put in a “safe mode” and all activities on-site (including
LS2 projects) were suspended teleworking
• Remote teleworking was beneficial and productive for the majority but less relevant
for colleagues doing mainly hands-on work. Important also to keep social
connection with “isolated” colleagues (stay-at-home order for France).
• Focus on training, documentation and technical specification for tendering process
(new target vessel contract, nano-laboratory equipment….)
• Continue the excellent collaboration with all ISOLDE stakeholders (standing
meetings maintained and additional ones).
• Ensure proper representation of ISOLDE in CERN wide committees. Very important
when discussing priorities and support from technical teams.

CERN plan for restart
Special LS2C LS2 Day
8th May 12th June
End-June
For EN-STI-RBS:
Phase 1 Phase 2 • Priority for frontends production
• Workshop activities
• Target production
• MEDICIS operation
• Students experiments (TISD)
• End of June, ~10 people on site
out of ~20 (rotation)
People with symptoms
Safe-mode and other Resume gradually, starting Ramp-up to “unlimited” or vulnerabilities not
urgent activities with LS2, accelerator and access may be completed allowed to work on site
detector upgrades, urgent by mid-September
site and building work

FE10 production status (installation on GPS)
• FE10 in Building 179 successfully vacuum tested during the last weeks
• Preparatory activities (alignment, cabling….) inside the GPS Faraday cage in view
of the Frontend installation
New irradiation table GPS Faraday Cage
FE to the target area
Stable beams

• Stable beam testing period at offline2 starting in August
• New contract for J. Cruikshank until end of Jan. 2021 (+ 6 months, exceptional circumstances)
